Problem with formatKey using java.lang.Double that works with primitive double
I have been using Struts extensively in my applications for several years and recently noticed some strange behavior. I format numbers and dates as follows: This is used in hundreds of places throughout my application and works fine if the value is java.lang.Double, but recently this started acting strangely for no reason. It will not format some values unless I declare them as primitive values. As soon as I change numTons on the release object it formats fine. I do not understand what is going on as I always use java.lang.Double and never use the primitive type in my objects. Why all of a sudden would this work in some places and not in others? Thank you for your time, Jason Long CEO and Chief Software Engineer BS Physics, MS Chemical Engineering http://www.supernovasoftware.com
Is session.setAttribute unique for all sessions?
In an Action, an attribute is set by
session.setAttribute("Privileges", userPrivileges);
If another session logins and the same Action is called again,
will the two sessions share the same attribute?
Thanks

RE: question regarding ActionForm
Niall,
I am using Struts 1.2.7.
Tomcat 5.5.9
OS - Window XP professional (with Service Pack 2)
I tried what you suggested me:
ProgramGroupForm pgForm =
(ProgramGroupForm)request.getAttribute(mapping.getAttribute());
pgForm.getType();//same problem, returned "null"
pgForm.getDescription(); //same problem, returned "null"
If I commented out the Http client call (and hard coded the result instead),
everything worked fine again.
I switched on the "debug" mode for log4j. The BeanUtils seemed to work
fine, it did copy the value correctly.
Is it possible that Struts get the wrong reference of the ActionForm object
and assigns it to both the Action's execute method and JSP page? (since the
debugging info showed the correct values).
Thanks,
Vince

Subject: Re: question regarding ActionForm
Firstly what version of Struts are you using? It probably doesn't make a
difference, but its always useful to know.
Could that call (or anything else) be affecting the attribute under which
the ActionForm is stored in the request? What happens if you retrieve the
ActionForm from the request after the service call [i.e.
request.getAttribute(mapping.getAttribute())] - is the ActionForm there and
OK?
One thing you might try is to "comment out" the call to your service in your
"SelectProgramGroupItem" action and replace it with something hard coded.
That way you can verify that it is actually the service call thats causing
the problem and not something else.
Have you checked your logs to see if anything is going wrong?
Another suggestion is to switch on logging in debug mode - the
RequestProcessor's processActionForm() method (which creates and stores the
ActionForm) logs what it does (in debug mode) - it should tell you the
scope/key that the ActionForm has been stored under. Also Commons BeanUtils
(which populates the ActionForm) logs every property that is set (in "trace"
mode) - would be useful to see if it is populating the description/type
properties OK there.

RE: Is session.setAttribute unique for all sessions?
In that case the scope of the variable is only to that particular session. If
some one else logins and the same action is getting called then the data will
be available in a separate session. If there is a concurrent access then you
need to check how you are creating the session object also. very first time you
need to create the session object by passing the "true" parameter and in all
other cases you need to fallow "false".

From the bits of code you've posted, everything looks fine, although you'll forgive me from being skeptical - but people don't always post exactly the code they're running. If its a Struts issue its more likely that the ActionForm you're mapping is configured to use is different from the the action mapping used by the element in the jsp. Other things that could cause trouble include "Action Chaining" or a custom RequestProcessor thats messing with the default behaviour. I would concentrate of what the http client call is doing though - that is where the issue seems to be caused.

RE: [Hibernate] Who owns the problem?
Murray,
I'm with Martin. I'd be more likely to skip your call to createQuery():
session.createQuery("from com.pancakes.website.controller.form.SectionForm
order by seq").list();
And instead use something like this:
session.find("from SectionForm s order by s.seq").list();
Why? You shouldn't need the full name and createQuerys are best used if you
have to do things like set parameters, choose min or max results, and so
forth. Since I'm not seeing that in your query, I recommend using find().
Plus, you shouldn't need the full class name unless you have two object
classes named SectionForm but in different packages. On top of that, I
recommend putting your query in an XML file as a "Named Query" so you can
update it without having to recompile your java code, should the need ever
arise. Also, you should probably re-read the Hibernate 2.0 (still relevant
in 2.1 and 3.0) tutorial chapter on manipulating data which covers gets,
saves, updates, and the various query types at the url:
http://www.hibernate.org/hib_docs/reference/en/html/manipulatingdata.html

Excel Download - Multilingual Data
Hi,
In one of our STRUTS Application, we provide excel download for the
users in worldwide.
We get all the data from data layer and write that string-buffer into
the client using the content type as follows.
response.setContentType("application/ms-excel;");
response.setHeader(
"Content-Disposition",
"attachment; filename=\"Sample.xls\";");
BufferedWriter out = new BufferedWriter(response.getWriter());
out.write(dataBuffer.toString());
out.close();
The issue is some of the German users having the regional settings for
decimal numbers as comma and they set the browser locale also as German.
When we send the locale-formatted-data to the client side (excel),
everything looks good.
Other side, some of the German users has the control-panel ->
regional-settings for decimal numbers as comma but they set the browser
locale as English.
So when we send the browser-based-locale-formatted-data to the client
side (excel), data getting screwed up. Because we send English numbers
and the excel expects the German data.
Question is, is there anyway we can detect the client Regional setting
in our STRUTS server side?
Other question is, can we set the data-category for the excel columns
when we send the response to the client side (always the data going as
Number-General)
I know that this is not cent percent related with STRUTS, but as we have
many gurus in this forum with multi-lingual app background, I thought of
getting the advice.
Thanks in advance.
Re: Problem with formatKey using java.lang.Double that works with primitive double
> It will not format some values unless I declare them as primitive values. > As soon as I change numTons on the release object it formats fine. > Interesting. The tag will use the PropertyUtils.getProperty() to the value for that property and then format it. The getProperty() of PropertyUtils returns a java.lang.Object and so even if the property is defined as a primitive the corresponding Object wrapper will be given back for formatting. The will format unless the value from the getProperty() is resolved to a java.lang.String. So, I think it should behave the same if you use java.lang.Double or a primitive double. I would try from a test-case what the type of the object that is being returned from the call PropertyUtils.getProperty(inventoryStatusForm, "released.numTons"); when a java.lang.Double and a primitive double is used for numTons. And if they are different from java.lang.Double, there should be something which should be confusing PropertyUtils. Just curious. What version of beanutils and JDK do you use?

Mahmoud-
If your webapp is called foo, create a file
$TOMCAT_HOME/conf/Catalina/localhost/foo.xml
You will need to match the exact name of the identified resource contained
within foo.xml
later on you will reference
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
if(envCtx == null )
throw new Exception("Boom - No Environment Context");
// the following matches the resource name defined in foo.xml
DataSource ds =
(DataSource) envCtx.lookup("jdbc/sampdb");

Subject: Datasource not found by Plugin on startup
Hi,
I have written a plugin for a Struts app which accesses a DB connection via
a datasource. The datasource is defined in the Tomcat server.xml file, and
is loaded via a library we wrote. I know the datasource works fine because I
can access if from other classes in the app. But when I start up Tomcat, I
get the following exception thrown:
javax.naming.NameNotFoundException: Name jdbc is not bound in this Context
Is there something I need to do to make the DS available to my Plugin?

maxFileSize validation
I'm just wondering if anyone has a workaround or suggestion for the following "bug": http://issues.apache.org/bugzilla/show_bug.cgi?id=36687 Properties, request params, request attributes are all null when the file submitted in the file field is greater than the maxFileSize setting in the struts config controller element. (default 250Mb). So that when the form bounces back with the validation error for exceeding the max file size, the other required properties (like text fields that were filled in) are not refilled and erroneously giving validation errors.

Hibernate domain / DTOs in JSPs.....
Has anybody got any experience of using Hibernate pojos with nesting & lazy loading in their JSPs in an enterprise app? Are there any caveats? I have always transfered the data from Hibernate beans into my own form beans or bespoke view DTOs in my actions, until now. It seems nice and easy to develop especially with JSTL & EL, but I'm still slightly worried about coupling the view so closely to the domain model, and potential scalability / robustness issues.

Yes, you must be quite careful to preserve an open session throughout the entire view, or to use Hibernate.initialize() on everything which might otherwise not be initialized. If you're used to transferring data, then calling initialize() might not be so bad, but really, most people use the "Open Session in View" pattern to manage a session using a ServletFilter (or equivalent, google will turn up all the necessary info on that). In my experience, there can be some kinks to work out within your mappings and your access patterns, but so far, I'm happy (of course, the closer the deadlines come, the more annoyed I may be at the usually pleasant challenge of solving some new technical puzzles!) But in my application, I have a very rich object model, and the labor of copying everything around instead of using it directly seems extremely tedious. (Note that my typical design strategy would not have led me to as much concern as you have already demonstrated by posting this, so YMMV.) It seems nice and easy to develop especially with JSTL & EL, but I'm still slightly worried about coupling the view so closely to the domain model, and potential scalability / robustness issues. If you use the lazy loading correctly, you probably deal with most all of the scalability and robustness issues, but again, there is definitely learning required along the way, so budget time accordingly or save it for a project when you can.

[Shale]Newbie question
Hi, after long time of scepticism I decided to try out Shale. I downloaded the shale nightly and installed it on my tomcat 5.0.28. Somehow it was not very satisfying. The struts-shale-usecases runs (or I suppose it to run) with a lot of warnings, but dont give the example, an application developer need. Are there other example applications? One thing I noticed, every link (in the resulting html) is a form submition. Is there a way to configure it? Because, if not, it would be an absolute NOGO, since it would make the site uncrawlable (at least for modern search engines). Where is the best place to start with Shale? regards Leon P.S.

Re: Getting at exceptions in Action Classes when forwardedfromweb.xml?
Even then, is there any way to get at the exception at self so it gets printed? The problem is that when you setup web.xml to send it to an action (I can't figure out a different way to do this that is fairly simple) it's almost like the app server swallows it for the most part and passes little information to the action. I can do things like pass along the number of the error in the querystring... 404 /error.do?exception=404 But other than that I can't figure out how to get at the actual exception so I can log that.

RE: question regarding ActionForm
The Http client call is a third party software, unfortunately I don't have its source code to debug it. I tried to deploy the app in Tomcat 5.0, but it couldn't run due to some methods missing in the xml parsing library. My app is just a small part of the overall app, and they are all programmed to run in 5.5.9, therefore making it to run in 5.0 won't be useful. Is there any possible way in struts that I can make sure it assigns the right reference of the ActionForm object to the Action and JSP page? Under what circumstances, the Struts's handling of the ActionForm got messed up? I had already made sure there isn't any action-chaining used in the app. The only thing I can't make sure is, if the third party software that I used (which makes the http client call) changes RequestProcessor default behavior. It is not likely, since it is not a Struts based app. Thanks, Vince -Original Message- From: Niall Pemberton [mailto:[EMAIL PROTECTED] Sent: Monday, October 03, 2005 9:14 AM To: Struts Users Mailing List Subject: Re: question regarding ActionForm From: "Vince Law" <[EMAIL PROTECTED]> Sent: Monday, October 03, 2005 9:09 AM > Niall, > > I am using Struts 1.2.7. > Tomcat 5.5.9 > OS - Window XP professional (with Service Pack 2) > > I tried what you suggested me: > ProgramGroupForm pgForm = > (ProgramGroupForm)request.getAttribute(mapping.getAttribute()); > pgForm.getType();//same problem, returned "null" > pgForm.getDescription(); //same problem, returned "null" Did you do this after the Http client call?

(since the > debugging info showed the correct values). Its hard to see how this could happen - its such a core part of Struts that if it wasn't working I think we would be inundated with issues. From the bits of code you've posted, everything looks fine, although you'll forgive me from being skeptical - but people don't always post exactly the code they're running. If its a Struts issue its more likely that the ActionForm you're mapping is configured to use is different from the the action mapping used by the element in the jsp. Other things that could cause trouble include "Action Chaining" or a custom RequestProcessor thats messing with the default behaviour. I would concentrate of what the http client call is doing though - that is where the issue seems to be caused. One last suggestion, and I'm not sure why I'm saying it, but can you deploy this on Tomcat 5.0 rather than 5.5 and see if it still occurs? > Thanks, > Vince - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Getting at exceptions in Action Classes when forwardedfromweb.xml?
I dont know if this is how you *have* to do it, but it's how I do it...
I have the same requirements you enumerate here, and this is how I
accomplished it. Works very well. What you have essentially is a class
that looks a lot like an Action (but isn't actually one... look at the
execute() signature... identical except for the Excepion being passed in
too) that you can do whatever you like in. Then you forward to a JSP.
Here's an example from one of my apps, cut down a bit... probably more
than your really interested in, but it gives you an idea of what you can
do...
public class GlobalExceptionHandler extends ExceptionHandler {
public ActionForward execute(Exception e, ExceptionConfig config,
ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws ServletException {
if (log.isDebugEnabled()) {
log.debug("GlobalExceptionHandler.execute(): " + e);
}
ByteArrayOutputStream baos = new ByteArrayOutputStream();
e.printStackTrace(new PrintStream(baos));
HashMap attributes = AppHelpers.getRequestAttributes(request, true);
HashMap parameters = AppHelpers.getRequestParameters(request, true);
HashMap headers = AppHelpers.getRequestHeaders(request);
HashMap sessionAttributes =
AppHelpers.getSessionAttributes(request, true);
request.setAttribute("error_attributes", attributes);
request.setAttribute("error_parameters", parameters);
request.setAttribute("error_headers", headers);
request.setAttribute("error_session_attributes", sessionAttributes);
HttpSession session = request.getSession(false);
String userID = "Unknown";
String clientCode = "Unknown";
if (session != null) {
HashMap userInfo = (HashMap)session.getAttribute("userInfo");
if (userInfo != null) {
userID = (String)userInfo.get("userID");
} else {
userID = "userInfo was null, could not retreive";
}
HashMap activeClientInfo =
(HashMap)session.getAttribute("activeClientInfo");
if (activeClientInfo != null) {
clientCode = (String)activeClientInfo.get("clientCode");
} else {
clientCode = "clientCode was null, could not retreive";
}
} else {
userID = "session was null, could not retrieve";
clientCode = "session was null, could not retrieve";
}
String path = "Unknown";
if (mapping != null) {
path = mapping.getPath();
} else {
path = "mapping was null, could not retreive";
}
String node = "Unknown";
try {
InetAddress addr = InetAddress.getLocalHost();
node = addr.getHostName();
} catch (Exception ee) {
node = "exception occurred, could not retrieve";
}

The exception mapping is a global forward that winds me up in
eception.jsp, which displays most of the information you see dumped to
the log above (not all of it... some of it is potentially sensitive).
You get the idea though. This will handle any exception on the
server-side, except for JSP error. But, obviously you shouldn't ever
get a JSP compile-time error in a production app, and if you've coded it
half-way decently you should never get a runtime exception either (I
can't remember the last time I saw a runtime JSP exception).

Re: question regarding ActionForm
Your previous answer seems to point to the culprit being the call to the third party software - as you don't have the source then maybe you should contact the third party to see if they can shed some light on this issue. I doubt the issue is Struts messing up the reference of the ActionForm passed to the Action's execute method or stored in the Request - it might be because of whats configured in your struts-config.xml or what you have in the element of your jsp not being right. But that wouldn't add up with what you say is happening after the http client call - and theres nothing to indicate any issue in the snipets of code you've posted. Sorry, I'm out of ideas.

Re: Getting at exceptions in Action Classes whenforwardedfromweb.xml?
Oh I see, sorry. That would be a tomcat thing. I have a suspicion that there may never be an exception. Tomcat (or your appserver) is just creating an error - that doesn't mean that it actually threw a Java exception. I believe that it is merely a status for the http response packet. The text that appears in the browser is purely browser-dependent. So basically a real live java exception would tell you no more than you already know, except perhaps if there is one, a stacktrace from the guts of your appserver.

RE: [Shale]Newbie question
Leon, The point you made about Shale performing form submissions is more of a JSF (JavaServer Faces) issue to help it retain state information to properly generate, validate, and so forth the JSF pages. I don't believe Shale tries to make JSF navigation any different. I have seen some discussions on using simple urls (for bookmarking purposes, etc.) that are compatible with JSF over on the MyFaces user discussion list. I recommend you subscribe to that list or read their archives online such as at http://www.mail-archive.com/users%40myfaces.apache.org since MyFaces is an open source JSF implementation.

Shale is a framework built on top of JSF. It provides value added features that are not in the vanilla API. If you are not fimillar with JSF, you will really have a hard time seeing the value added features of Shale. > One thing I noticed, every link (in the resulting html) is a form > submition. Is there a way to configure it? The commandLink component is used on the usecases entry point menu page. A outputLink could also be used which generates a HTML anchored tag. The one reason that the commandLink navigation was used in the usecase menu page was to demonstrate the use of the ContextRelativePathFilter.

Re: Getting at exceptions in Action Classeswhenforwardedfromweb.xml?
This actually does get me some of the information. Unfortunately since I'm sticking another servlet (my action) in between, the exception acts like it's coming from my action. So it appears I may have to go the route of extending the ExceptionHandler. I was hoping there was a way to avoid that, but it doesn't appear so.

I was hoping to find an example application like the mailreader (I thought it has been rewritten for Shale, at least someone was announcing it on the list).

You mean, coming in with a non-functional link with some parameters? That's not a problem, you can detect it pretty early in the base action (filter whatever). The problem is, that if all your links are posts, you will be considered as not-interesting content by the search engine (only one url, different context).
